Chapter 10, Problem 11RA
Summary Introduction
To determine:
The processes involved in viewing objects at a distance.
Introduction:
Eyes are the sensory organs that provide vision. The eye has three main layers, ciliary muscles, and a biconvex lens that are together involved in the function of vision. The layers are sclera, choroid, and retina. The retina contains photoreceptor cells, rods, and cones that respond to the different wavelengths of light.

Which of the following statements are true of the parts of the eye? (Read carefully and select all the correct statements.)
A.
Vitreous humor is reabsorbed into the canal of Schlemm.
B.
The radial muscles of the iris constrict the pupil.
C.
The white of the eye is formed by the sclera.
D.
The choroid layer absorbs light within the eyeball.
E.
The conjunctiva is kept moist by tears secreted by the lacrimal glands.
F.
The retina is the innermost layer of the eyeball.
G.
